Two notoriously dangerous intersections in San Francisco's Inner Sunset neighborhood are on the fast track for pedestrian-safety upgrades.

City officials have proposed installing pedestrian countdown signals at Ninth Avenue and Irving Street and Ninth Avenue and Judah Street to let people know how long they have to cross the street. In addition, when Municipal Railway light-rail vehicles arrive at those intersections, the traffic signals would be triggered automatically to give the streetcars an exclusive right-of-way.

A 90-year-old woman was severely injured when she was run over by an N-Judah streetcar at Ninth and Irving on Jan. 7.

Officials hope to begin the installations this month, pending funding approval. Staffers with the Transportation Authority, which allocates sales tax revenue to pay for transportation-related initiatives, has recommended spending $190,000 on the Inner Sunset project. The authority's Plans and Programs Committee is scheduled take up the proposal Tuesday, followed by a vote of the full board of directors on Feb. 12.
